Display Options:
Attribute: Select the attribute class from which you would like to determine the
color and shape of symbols to be displayed.
Check the Use average value per attribute option if you want to display a single
symbol for each class reflecting the average values of dip and azimuth. A single
point is drawn rather then a cloud of points.
Poles: As the user can display the data as density plot (contour plot) or great circles,
poles are displayed only if the corresponding Poles option has been checked.
Great circles: If the great circle for each pole should be displayed the user has to
check this option.
